. ein FILTER.

My invention relates to oil filters and .has for one of' its objects the provision of :i simple end eliicient iilterini` mechanism adapted to permit the easy flow of oil to bearings, and the like, without trappingr or pocketing.

it further object is the provision oi! e filter receptacle mounted on a pedestal which may have branch lines taken therefrom permit-- ting` the oil to flow down hill to desired bearings, and the like.

@ther objects will appear hereinafter.

ein embodiment of my invention is illustrated in the accompanying' drawing, fermine; apart of this specihcation, and in whichliie. 1 is a vertical section taken through a filtering,1 apparatus embodyingl my ini/ention; and l Fig. 2 is a section taken on line 2-2 of. Figi'. 1.

Referring more particularly to the .drawing', a filter receptacle or tank 3 is indicated us being' cylindrical, but may be ot any preferred design. Disposed within the receptacle 3 is. a well or water separating` chamber 4t extending from the bottom to the top of the receptacle 3. Through the bottoms oi receptacle 3 and well Il entends 'n supply pipe 5 which is adopted to conduct the impure oil into the well Through one or more openine's 5 nier 'the bottom ot well l a stem .entends up from the litt o' the openingl 5 thereinand has s top for an justine'` sai d fitting' in position, but said stein and handle may be dispensed with when so rThe well l may be urrangged iu the o 1' am' desired manner., the tubular 'term show: iuiikirie; :in eilieient and economical construciion. ifi removable 'liaugled lid or cover is shown at 29 to serve. as a closure vtor the top oli the tank 3 and to permit renewal ot the 'filler elements when desired.

llesr the top oit well i ure discharge pipes 7. As many pipes Z will be provided there are filter-elements, to be described later, in the recent-ticle 3. Water in the impure oil comino; :trom pipe 5 will settle to the bottom oii well 4t and the oil and certain impurities will ren/min on 'topV rlhis water and such impurities as sett-lolo the bottom oi the weiter seperating` chamber may be drown oll through valve 4.4 rlhe impure oil will pass out through the pip-es 7 where it will be discharged into filter elements 8. These filter elements may be oi' any desired construction, such as that shown, which is substantially that disclosed in my United States Letters 1922. Serial No. 562,083.

Patent No. 1,044,074, issued November 12, 1912. The oil upon passing thirough the filter elements 8 falls to the bottom oi receptacle 3 where it is drawn oil for use.

At the top ofwell L is an overflow pipe 9 which extends across and downwardly in the receptacle 3 and has its discharge end connected with a tray 10. A pipe 11 is connected with the tray and extends down through the bottom of receptacle 3 to cerry overflow liquids from the device. The intake opening or pipe 9 is placed well above the discharge pipes Y and low enough to prevent the well i from overflowing into the clean oil in receptacle 3.

Above the tray 10 is a closed casing` or mete-.l boi; 12 in which is a shait 13 pivotally carrying' a tiltuble pan 14. rlhe shaft 13 also has an arm 15 which makes electrical contact with a stop 16 in the member 12. An alarm device l'is mounted on the housing` 12, and the parts 12 to l?, inclusive, may be the same as forth in my pendin application, Serial No. 393,575, filed July 2, 1920, for overtlow alarms for lilters.

ln the structure shown in the eccompanydrawings the source of current for the electrically operated bell 17 is in the form oic a dry cell 3() in the casing 31. Onelterminal of thedry cell may-be connected to the metal casi; e A2 and therefore to the metal shaft 13 und the metal counterweigght arm 15. The other terminal 32 oit the 'dry cell may be connected to the electron agnetic mechanism ot the :il rm 1T which in turn is connected to ulated Contact 16. Normally the pun ,i and the counterweight arm 15 down sind lhei loro the circuit is broken at the contact 15S, but when overflow from either or both of the iilter elements occurs the circuit Yfrom the dry cell will be completed to operate the electro-niagnetically operated bell of welllniown type and construction.

Above the member 12 is a tray 18 large enough to catch the overflowing` oil 'from spouts 19 oi the filters 8. il pipe 2O connects the tray 18 with the casing 12 and provides means for drainingl seid tray into the pun 14- in lioiisinel 12. Should the :filters 8 become clogged, the oil instead of running through the filters would run out et spouts 19 into tray 18 end down through opening .2O into pan 141, tilting the latter on shaft 13, bringingg the parts 13, 14 and 15 to the positions shown in 1. This would .set into opera tion an electric signal as above described to is suitable for use lubricatiniY attract the attenda'hts attention to Ythe. fact that the filtering nieclianisiii 8v not fund tioningl properly. @il after leaving" 14 would run down through al .suitable opening in the bottoni ot casing-12 into tray lO and thence down through pipel1 out of opening 25. y Y

lt should be noted that it the alarin inech# anisni is oinittcd teinporarilyor otherwise the spouts 19, shown in Fig. 2, in position to direct ovei'iio'w to the tray l0.

. The filtering' apparatus above referred to m niany kinds of machinery and r ay be used in such aconstruction as set forthin n'iy United States Letters Patent No. 1,267,067, issued December 5, ltl; for' continuous ailingr and filtration apparatus. ln such devices requiring' lubrication,A oftentimes parts oi. theseA deificcs are quite high and iii pipes conducting' oil to thein w'ei'ierun down low and then raised up to the parts reep-urine` the oil, pockets would be formed in the pipes preventing the ready flow of the lubricant tol these parts oit' the ina'- chine'ry. My present iinproveinent consists in inounting the tilterine apparatus yon a hollow pedestal which is in communication with the clean oil et the tilter receptacle so that this y pedestal may have branch pipes extending therefrom at heights permitting the oilto run down hill all the way to the parts requiring lubrication. I therefore ,provide a tu-l bular pedestal 2l which may be attached to A the bottoinot receptacle 3 in any desired manner; such as by the threaded connection 22 shown. i

, At the bottom ont the pedestal 21 is a litting 23 having a partition 24 therein, andthe fitting at one side of partition 24 is connected with lpipe ll so that the liquids discharged through the pipe ll may leave the iittinp,- 23 through :opening The other side of the Yittiiig' n28 inl communication with the interior oiz the pedestal 2l and .is adapted to discharge clean oil through opening 2G in said fitting'. The openingr 2G inay be connected with any part ot the lubricating system shown in my United States Letters Patent No. 1,207,067, above referred to, or other devices requiring lubrication. rlhe pedestal 2l may have branch pipes 27 taken ott at any height in the pedestal so las to perinit con-. ducting` the oil downwardly to the higherv parts ot the devices to be lubricated. This perinits the oil 'to run down to the parts requiring lubrication without the likelihood of forming' traps or air pockets to retard the flow oi lubricant.4

Itv should be noted that the litting 38 having the branch pipes 27inay be threaded to the upper pipe section 2l and tothe lower pipe section 3L The latter inayfbe connected to the bottom yT-litting 23 by ineens ot the tubular joint 85. It willthus `be seen that by varying,` the lengths ot' the pipe sections 2l and 34 the branch pipes 27 inay'be adusted to various heights while the height ofthe tank 3 and the height ot the T-titting 23 reniains the 'saine'.` The pipes leadingl to the lubricatingnozzles in the system inay be connected to 'the branch pipes 27 and also to the lower 'branch pipe 23, or the latter inay be. closed with a screw plug 'and the upper branchpipes 27 used. In any event it is desirable to have the oil pass by gravity'froin the tank 3 to the places where distribution of the lubricant' is desired.
